Turntable Shot Blasting Machine for Flat Metal Parts
Product Introduction

Rotary table shot blasting machine loads workpiece by turntable. According to the diameter of turntable, it can be divided into 1 200 mm, 1 600 mm, 1 800 mm, 2 2500 mm and so on. The shot blasting machine can be equipped with single or multiple shot blasters according to workpiece products, etc. Its working principle is: the workpiece is placed on the turntable (there is a distance between the workpieces, no contact, no collision), the turntable takes the workpiece into cleaning area for shot blasting cleaning, when transferred to the position of the placement, the workpiece can be removed. Therefore, this type of machine is most suitable for the workpiece one side without cleaning, otherwise the workpiece should be turned over and cleaned again.

Application

Surface cleaning or strengthening of medium and small-sized castings and forgings in the industries of gear, gear shaft, forging, casting, construction, chemical industry, motor, machine tool, etc., such as removing oxide scale, burr, sand casting, etc.

Outstanding Advantages
  • Using Wear-resistant rubber track+manganese plate;
  • Using advanced wet dust collector system;
  • Using crushed shot secondary separation system;
  • Using high performance P series impeller head (die steel CNC machining + vacuum heat treatment);
  • Using steel shot flow semi-automatic control system;
  • Using automatic turntable system
  • Optional: Magnetic sorting system + spiral pusher sorting + air separation sorting system;

Working Principle
Rotary table shot blasting machine loads workpiece by turntable. According to the diameter of turntable, it can be divided into 1 200 mm, 1 600 mm, 1 800 mm, 2 2500 mm and so on. The shot blasting machine can be equipped with single or multiple shot blasters according to workpiece products, etc. Its working principle is: the workpiece is placed on the turntable (there is a distance between the workpieces, no contact, no collision), the turntable takes the workpiece into cleaning area for shot blasting cleaning, when transferred to the position of the placement, the workpiece can be removed. Therefore, this type of machine is most suitable for the workpiece one side without cleaning, otherwise the workpiece should be turned over and cleaned again.When shot blasting, steel shot from this process fall down to the bottom of the shot blasting chamber then the steel shot is transported to the bottom of the elevator by the screw conveyor, and then to the top of the sorter by the elevator belt assembly respectively. The sorter is powered by the dust collector. The purpose is to separate broken steel shot and dust from the shot blasting processing. Through the sorting device, qualified steel shot will come directly into the storage bin above the blasting machine, and ready to be used again. Shattered Steel pellets will be separated again and dropped into the waste cylinder through the sand pipe. Dust is directly sucked away by the dust collector fan and adsorbed in the filter dust collector; finally dust falls into the dust recovery box that needs to be cleaned up regularly.
Product Description
1Shot blaster

1. The blasting machine motor adopts ABB with excellent and controllable manufacturing process, good sealing, good dynamic balance and stable and reliable performance advantages.

2. The blasting machine outside shell is made of 10mm high-quality carbon steel plate by laser cutting and precision bending. The shell is welded by special fixture to ensure the parallelism of the two sides of the blasting machine shell and the concentricty of the hole.

3. The top guard plate is precision machined by die steel CNC, and the machining precision is ±0.01. After machining, low pressure vacuum heat treatment is adopted.

4. End guard plate is made of high wear-resistant manganese 13 steel plate by laser cutting.

5. The side guard plate is precision machined by die steel CNC, and the machining precision is ±0.01. After machining, low pressure vacuum heat treatment is adopted.

6. The Orientation sleeve is precision machined by die steel CNC, and the machining precision is ±0.01, with uniform wear and good balance. After machining, low pressure vacuum heat treatment is adopted.

7. The Pill wheel is precision machined by die steel CNC, and the machining precision is ±0.01, with uniform wear and good balance. After machining, low pressure vacuum heat treatment is adopted.

8. The blades is precision machined by die steel CNC, and the machining precision is ±0.01, with uniform wear and good balance. After machining, low pressure vacuum heat treatment is adopted.

9. The impeller is precisely machined with CNC die steel, and the machined precision is (+0.01). The surface hardness of the impeller can reach HRC58-62 by vacuum heat treatment under low pressure after machined.

10. The service life of the above vulnerable parts is more than three times as long as that of the casting products (shot material: less than S460 (1.5mm cast steel shot), hardness: HRC40-50).

2Flow valve

1.Semi-automatic flow control system, used to control the flow of shot into the shot blaster, the flow of steel shot is adjusted manually.

2. Fully sealed structure design, with lockable inspection openings and two bearing

3. The upper end of each flow valve is equipped with a manual globe valve. If the flow valve needs to be repaired, it can be closed so that close the steel shot flowing from the silo for easy maintenance.

3Shot blasting room

1. The shot blasting chamber is welded with all manganese steel.

2. Several manganese steel protective plates are installed in the hot zone of shot blasting chamber, which are located in 3/4 of the direct shooting area of the shot blaster. They are fixed by suspension, simple to install and easy to be disassembled and replaced.

3. A three-layer sealing structure is installed at both side of turntable to prevent the steel shot leaking from the top during shot blasting operation.

4. The driving mechanism of the main turntable is located at the top of the shot blasting chamber. It is driven by a 1.5 kW deceleration motor to rotate 180 degrees. The two small turntables are located at 180 degrees, respectively. The reducer is driven by the cylinder, and the tooling rotates 360 degrees through the meshing and rotating motion of the gears.

4 Elevator system


1. The elevator is used to lift the steel shots recovered by the screw pusher into the separator and silo.

2. The elevator is made of precisely welded steel plates and can be disassembled in segments. Maintenance and inspection windows are provided for easy maintenance.

3.A drive and deceleration motor is located at the top of the hoist, which acts as the power source of the elevator.

4. The system consists of two precision-machined hubs, one hoist case, one high-performance wear-resistant belt and several alloy hoists formed by one stamping process.


5Turntable system

1. The driving mechanism of the main turntable is located at the top of the shot blasting chamber. It is driven by a 1.5 kW deceleration motor to rotate 180 degrees. The two small turntables are located at 180 degrees, respectively. The reducer is driven by the cylinder, and the tooling rotates 360 degrees through the meshing and rotating motion of the gears.
